Screenwriters had decided to change one of the character's names to Tatty after "long and careful discussions"

Chris McGovern, chairman of the Campaign for Real Education, said the name-change represents giving in to political correctness.
He said: "It is surrendering to preconceptions about how children think.

"If there is a problem with how children think they need to deal with the problem not sort of adjust things. I think they should respect the integrity of the book and keep the original name in my view.
"It’s basically giving up and saying “we can’t cope with this so we’re going to change the name.

"It’s a surrender to political correctness.

"Children who see the name and realise they’ve changed the name might create more problems."
